Blender won't start, while I used it before on this machine
Blender recently switched to opengl 2.1 so you will need to upgrade your hardware to support opengl 2.1 or switch to an older Blender version. The last version to support older versions of opengl is blender 2.76.

You can find a note about that in the release notes of Blender 2.77
